Limit shape for regularisation of large partitions under the Plancherel measure

Salim Rostam

A celebrated result of Kerov-Vershik and Logan-Shepp gives an asymptotic shape for large partitions under the Plancherel measure. We prove that when we consider -regularisations…

Core size of a random partition for the Plancherel measure

Salim Rostam

We prove that the size of the e-core of a partition taken under the Poissonised Plancherel measure converges in distribution to, as the Poisson parameter goes to infinity and after…

Skew cellularity of the Hecke algebras of type

Jun Hu, Andrew Mathas, Salim Rostam

This paper introduces (graded) skew cellular algebras, which generalise Graham and Lehrer's cellular algebras. We show that all of the main results from the theory of cellular alge…

Identifying Young diagrams among residue multisets

Salim Rostam

To any Young diagram we can associate the multiset of residues of all its nodes. This paper is concerned with the inverse problem: given a multiset of elements of Z/eZ, does it com…

Morita equivalences for cyclotomic Hecke algebras of type B and D

Loïc Poulain d'Andecy, Salim Rostam

We give a Morita equivalence theorem for so-called cyclotomic quotients of affine Hecke algebras of type B and D, in the spirit of a classical result of Dipper-Mathas in type A for…

Stuttering blocks of Ariki-Koike algebras

Salim Rostam

We study a shift action defined on multipartitions and on residue multisets of their Young diagrams. We prove that the minimal orbit cardinality among all multipartitions associate…
